slice cannot be hashed which make some operations significantly more annoying. see https://groups.google.com/forum/#!topic/comp.lang.python/SvhkWwSDeIw |

Please re-upload the patch file as an uncompressed text file, as it is quite difficult for many people to view zip files in their browser. |

This is a reasonable use case. +1 for making slice() hashable. Will, you're welcome to submit a PR. If not, I'm sure someone else would be happy to scoop this up :-) |

I think slices were explicitly made not hashable to avoid issues to avoid issues with dictionaries, see discussion at https://mail.python.org/pipermail/python-list/2001-March/076101.html and issue 408326. The commit that did this is https://github.com/python/cpython/commit/a1351fbd884189329bbcb6c688ca992fc1afc3f6 Is this not needed anymore? Wouldn't this need to be discussed on python-ideas? |
